Mortal Kombat game first appeared on SNES and Genesis. One had blood and the other didn't.

Trilogy appeared on the N64 and was great too(IMO)

But yes Part 2 was the best (IMO). I got this game on Xbox 360 live Arcade, and was great. I rather the PS controllers for fighting games tho. Always will. Them combos so so much easier to pull then on the 360 D-Pad.
